FIE 2021 Face-to-Face Conference Protocol:

  • The conference will follow Lincoln’s and Lancaster County’s present guidelines for Covid-19 safety (please be aware these are subject to change based on current conditions).
  • Conference attendees will be required to wear a mask during all conference events/sessions and all public areas of the hotel, whether they have been vaccinated or not. The only time masks can be removed is:
    • during a meal event;
    • when you are making your presentation, as long as you can maintain six feet distance from those in your session. If you are not able to maintain a six feet distance, then you will need to keep your mask on; and/or
    • for those individuals who cannot otherwise wear a mask because of a medical condition, a mental health condition, or a disability that prevents the wearing of masks.
  • Masks will be required when traveling to the off-site conference reception on the buses, as well as during the reception itself except when you are eating or drinking.
  • It is strongly recommended that you wear a mask at crowded outdoor events, but in general when you are outside a mask is not required.
  • Just so you are aware, in Lincoln and Lancaster County, all owners and operators of any building, business, or premises, other than a residence, shall require all individuals to wear a face mask while indoors. Everyone two years of age and older must wear a mask in these indoor settings, regardless of their vaccination status.

Creating a safe, worry-free experience is our top priority

The FIE 2021 conference Organizing Committee remains vigilant in monitoring the COVID-19 pandemic.  FIE is planned as face-to-face conference, but delivered with remote options to allow participants who, for a variety of reasons, may not be able to join the in-person conference in Lincoln, Nebraska, USA.


Keeping You Safe – Working closely with the Lincoln Marriott Cornhusker Hotel as well as Federal, State, and Local public health officials, we will incorporate required safety protocols to provide participants a safe, positive, and productive in-person experience to meet your goals.
